Shawn Porter’s father and trainer Kenny has revealed his continued frustration as British star Kell Brook inflicted a first defeat on his son to take the IBF welterweight title on home soil in California.

Brook, 28, nullified Porter’s work-rate to catch the judges eye at the StubHub Center, although Kenny doesn’t believe that ringside officials took into account the constant pressure put on the challenger throughout the contest.

“I could clearly see Shawn being more aggressive and landing more body punches,” Porter exclusively told World Boxing News.

“Shawn didn’t get the credit he deserved for his work and I did not agree with the decision.

“I don’t believe Brook was winning round with his excessive holding and I would absolutely fight a rematch in the UK.”

‘Showtime’ Porter lost for the first time in his career after initially pushing himself into the reckoning to fight Floyd Mayweather. Victories over Devon Alexander and Paulie Malignaggi had raised Porter’s profile considerably before Brook came along and the loss looks likely to see a Mayweather fight drop completely off the table.

A return with Porter doesn’t seem to be on the mind of Brook or his promoter Eddie Hearn though as both are looking at either Mayweather or Amir Khan for a huge unification or domestic super-fight in the spring of next year.

‘The Special One’ is set to have a stay-busy fight around December time in Sheffield in what will be a spectacular homecoming for Brook, although it is highly unlikely that Porter will be one of the opponents considered for the contest.
